Sensitometer
An instrument used to test the sensitivity of photographic surfaces. It produces a graduated series of exposures to light of controlled spectral quality, intensity, and duration.
Depending upon whether the exposures vary in brightness or duration, the instrument may be called an intensity scale or a time scale sensitometer.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
